Tinnitus is a ringing, roaring, whistling, hissing, humming, buzzing or other sound in the ear with no external source. If you get occasional bouts of tinnitus when taking a stroll through John F. Baldwin Park in the Baldwin Park Neighborhood, you may be experiencing what is known as sudden, brief, unilateral, tapering tinnitus (SBUTT). We review a study on SBUTT below.
About the Study
The study we’re discussing in this post was conducted by researchers in the Department of Otolaryngology–Head and Neck Surgery in The Edith Wolfson Medical Center at Tel Aviv University Sackler School of Medicine in Holon, Israel; Dalla Lana School of Public Health at the University of Toronto in Toronto, Canada; and Eaton Peabody Laboratory at the Massachusetts Eye and Ear Infirmary in Massachusetts, U.S.A.
There are actually two parts to this study, referred to here as Study I and Study II.
Study I focused on determining the effect of brief but intense jaw, neck and extremity muscle contractions on the auditory experience of participants in a room playing low ambient noise. They were asked, “Do you ever have a brief ringing in one ear, lasting a minute or less?”
Study II focused on participants who responded that they had experienced SBUTT previously. They were asked to keep a log of their symptoms over four months.
For Study I, somatic hearing tests revealed 20% of participants had existing tinnitus; 76% percent recalled having at least one episode of SBUTT in their lives; and 24% had no recollection of experiencing SBUTT. Of the subjects with existing tinnitus, 75% had experienced SBUTT, and of those with no ongoing tinnitus, 78% had experienced SBUTT.
For Study II, tests revealed that 20% had existing tinnitus. Those with existing tinnitus had twice the instances of SBUTT than those without existing tinnitus over the four-month period.
Both parts of this study reveal most of those who have chronic tinnitus have more instances of SBUTT, indicating a high rate of SBUTT may be a risk factor for chronic tinnitus.
